Application filed November 23, 1915.

To all whom it may Concern:

Be it known that we, LEONARD Niiiso): and HaaoLoXiLsoN, citizens of the United States, residents of lllayzata, county of Hennepin, State of Minnesota, have invented certain new and useful improvements in rTransmission-Gfearing, of which the following is a specification.

The object of' our invention is to provide a simple, compact gearing whieh can be assembled in a smaller space than gearings of this kind as usually constructed.

A. furthei-Hobject is to provide a transmission gearing Capable of Convenient operation and easilv accessible. v

@their objects of the invention will appear from the following detailed descriptlOTi. f

rlhe invention consists rious constructions and as hereinafter described pointed out in the claims. v

ln the aecon'ipanving drawings forming part of this specification, Figure l is a sectional view through a transmission gearing embodying our invention, Fig. is a` detail sectional view on the line {Uf-fs of Fig. l.

generalli,v in vacombinations`v all and particularlf/yv ln the drawinfr, 2 represents a suitable l housing of ordinary construction, having hearings 3 for a drive shaft 4 on which is mounted a driving pinion 5.

6 is a transmission gearing shaft .mounted in hearings in the housing at right angles,

substantially, to the shaft L A gear 7 having a hub 7 is keyed on said shaft 6 and aJ pinion 8 is loosely mounted on the huh of said gear and meshes with a gear of a differential 9 of usual construction having shafts l0 that are provided with sprockets ll for connection with the rear wheels of the vehiele in whieh the transmission gearing is mounted. The beveled gear 7 on the shaft G meshes with the pinion 5 and is provided with a series of openings 13 in its web. A hulo lelis splined on the shaft (3, being movable backand forth thereon through the clutch arms l5 in the usual way, and one end of-said hub is provided with a series of lugs lo in position to enter the openings 13 and engage the teeth 8' of the pinion 8 for the purpose of transmitting power inion S to the gear 9. A pinion 17 is provided at the other end of the huh 14 in position to mesh with a gear 18 when the hub Specification of Letters Patent.

from the shaft (3 through the' lllatented Aug. 8, 19t@ serial no. 63,020.

is moved in the other direction. These gears tl and 1S are connected with the differential 9 that is provided with the shafts 1G and being rf ordinariv construction, requires no detailed description or illustration.

i ll'hen the hub l-l is in the position shown in Fig. l., the gear will be neutral and the pinion .3 will drive the beveled gear T without transmitting power to the shafts l0. ldvheu, however. the pinion 1T is moved into mesh with the gear 18 of the differential` the power will he transmitted through these gears, to the shafts l() at slow speed and when the hub ,li is moved in the other direction, the lugs 16 will pass through the holes 1&3 and meshing with the teeth S of the pinion 8 will drive it and the gear 9 of the. differential and the shafts l0 at a faster speed. ln this way we are able to obtain two speeds in one direction through the movement of a single hub and pinion.

le claim as our invention:

l. ,i transmission gearing Comprising a transmission shaft, a gear mounted thereon having holes inits web, a pinion loosel7 mounted on said gear and having teeth in one end thereof. a pinion spliiied on said transmission shaft and having lugs to enter said holes and engage .the teeth of said loosely mounted pinion for one speed, and a gear mounted to mesh with the teeth. of said splined pinion for another speed.

In a transmission gearing, a shaft, a loosel)y mounted pinion, a driving gear secured on said shaft and having holes in its web, a pinion splined on said shaft and having means for engagement with the teeth of said looselY mounted pinion through the holes of said driving gear, for the purpose specified ln a transmission gearing, a shaft, a driving gear secured thereon, transmission gears mounted upon opposite sides of said driving gear and a transmission pinion mounted to move into engagement with the transmission gear on one side of said driving gear for one speed and through said driving gear into mesh with the transmission gear on the other side of said driving gear for another speed.

ln witness whereof, we have hereunto set our hands this 15th day of November, will.
